HI Seeks Reviewers For Updated Standard

16.04.2013

The Hydraulic Institute (HI), under the approval of the American National Standards Institute (ANSI), is seeking qualified individuals in North America to participate in the review process for the draft of updated Standard, American National Standard for Pumps – Controlled-Volume Metering Pumps for Nomenclature, Definitions, Application, and Operation (ANSI/HI 7.1-7.5)

ANSI/HI 7.1-7.5 has been revised and updated and replaces the prior version that was last reviewed in 2006. This standard applies to Controlled-volume metering pumps (also known as metering pumps, proportioning pumps, chemical injection/feed pumps, or dosing pumps) that are reciprocating positive displacement pumps typically used for the injection of chemical additives, proportional blending of multiple components, or metered transfer of a single liquid. These types of pumps are used in applications requiring highly accurate, repeatable, and adjustable rate of flow. Individuals and organizations located in North America directly and materially affected by this standard are asked to contact HI. These parties include pump users and specifiers, producers, standards developers, government agencies, and general interest groups. HI is currently assembling a canvass list of all parties interested in reviewing the draft. This list will be submitted to ANSI in order to meet its open canvass requirements.

HI Pump Standards are reliable, widely accepted references for anyone involved with pumps, including users, consultants, contractors, construction firms, manufacturers of pumps, seals, motors, instrumentation, controls, and pump software developers and systems integrators. HI periodically introduces new Standards based on industry needs.
